FAIR Data
Findability, Accessibility, Interoperability, and Reusability
Supporting discovery through good data management
Good data management is not a goal in itself, but rather is the key conduit leading to knowledge discovery and innovation, and to subsequent data and knowledge integration and reuse by the community after the data publication process
In Geological Survey context can drive growth and investment
FAIR Data
Findable The first step in (re)using data is to find them. Metadata and data should be easy to find for both humans and computers. Machine-readable metadata are essential for automatic discovery of datasets and services
Accessible Once the user finds the required data, she/he needs to know how can they be accessed, possibly including authentication and authorisation.
Interoperable The data usually need to be integrated with other data. In addition, the data need to interoperate with applications or workflows for analysis, storage, and processing.
Reusable The ultimate goal of FAIR is to optimise the reuse of data. To achieve this, metadata and data should be well-described so that they can be replicated and/or combined in different settings.
FAIR vs Open Data
FAIR data and open data are different, although there are similarities.
The key difference is that open data should be available to everyone to access, use, and share, without licences, copyright, or patents. It is expected that open data at most should be subject to attribution/share-alike licenses.
FAIR data, however, uses the term “Accessible” to mean accessible by appropriate people, at an appropriate time, in an appropriate way. This means that data can be FAIR when it is private, when it is accessible by a defined group of people, or when it is accessible by everyone (open data).
Metadata
"data that provides information about other data"
Represents the who, what, when, where, why and how of the resource
Solves most of the Findable and Accessible requirements of FAIR data
